Spin Valis holds a position of the local and regional leader in the production of high quality solid wood furniture, and its furniture is highly appreciated on European and world markets.
It's easy to see how this could get very confusing very quickly. Let's break it down so investors -- especially those who owned DowDuPont stock and now own shares of all three companies -- know what's in their portfolios.
DowDuPont's spinoffs are top companies in the chemical industry. Image source: Getty Images. While the old Dow and DuPont had many different product lines serving dozens of industries, the portfolios of both have been streamlined, leaving Dow with the bulk of the companies' "performance chemicals" assets.
These include a lot of names with which you probably aren't familiar. Paraloid ring a bell, anyone? Or Keldax? That's because most of these products aren't sold directly to consumers, but rather to other companies as components to finished goods.
Paraloid, for example, is an acrylic resin that increases impact and heat resistance. It can be used on furniture, concrete floors, or in paint among many other uses.
Keldax is a resin that can be used as an adhesive or as a sound barrier in automobiles. In physics and chemistry , a selection rule , or transition rule , formally constrains the possible transitions of a system from one quantum state to another.
Selection rules have been derived for electromagnetic transitions in molecules , in atoms , in atomic nuclei , and so on.
The selection rules may differ according to the technique used to observe the transition. The selection rule also plays a role in chemical reactions , where some are formally spin-forbidden reactions , that is, reactions where the spin state changes at least once from reactants to products.
In quantum mechanics the basis for a spectroscopic selection rule is the value of the transition moment integral . This integral represents the propagator and thus the probability of the transition between states; therefore if the value of this integral is zero then the transition is forbidden.
In practice, the integral itself does not need to be calculated to determine a selection rule. Otherwise, the transition is forbidden.
The symmetry of the transition moment function is the direct product of the parities of its three components. The symmetry characteristics of each component can be obtained from standard character tables.
Rules for obtaining the symmetries of a direct product can be found in texts on character tables. The Laporte rule is a selection rule formally stated as follows: In a centrosymmetric environment, transitions between like atomic orbitals such as s - s , p - p , d - d , or f - f, transitions are forbidden.
The Laporte rule law applies to electric dipole transitions , so the operator has u symmetry meaning ungerade , odd. The transitions are therefore forbidden.
The wave function of a single electron is the product of a space-dependent wave function and a spin wave function. Spin is directional and can be said to have odd parity.
